To complain? Kids activity

[PotentialComplainer]

My child does a martial art and had their first grading this week. Long story short I was told the wrong time and turned up to their group just finished and the next one, who are older, ready to start. Therefore my young child had to go in and do his first grading (which they were already nervous about) with children that he didn’t know and were pretty much double his size. He looks petrified going in the room and they were not sympathetic whatsoever. It was basically just right ok go in.
My knee jerk reaction was I am going to complain and drafted one while he was in. I find the poor level of communication unacceptable (especially for the price I pay!) so while I accept someone has made a simple mistake giving the wrong time slot, surely a professional organisation would provided letters or emails to confirm dates and times?
But I’m going back and forth with myself if it’s worth emailing a complaint now it’s done and over with.
YABU - don’t email
YANBU - email them

How were you told? Verbally?

Yes verbally when I paid at the front desk

I wouldn't personally, but if the person who told you the wrong time wasn't there then they should be made aware of their error. I feel bad for your child though, my DS had his first grading last week and was a nervous wreck.

It was a simple miscommunication, no need for complaints.
There's no harm in asking nicely that could the grading times be put on their Facebook page in future.

There is no Facebook page

Also can I ask how old is your child? I've noticed some activities stop communicating with the parents and rely on the child as they get older. While this is fair enough, it's confusing for some as my DS often gets info wrong and i need to double check whereas DD is always organised.

He is 5

What sort of set up is it? The martial arts clubs I have been involved in are volunteer run, and the fees, while not low, basically just cover insurance and hall hire.

I would absolutely not be complaining about this to volunteers.

I think it's all about tone.

I would raise it and ask that it be communicated more clearly next time, but I would try and do it in a friendly rather than complainy way. I'd not say 'I find the poor level of communication unacceptable (especially for the price I pay!)', for example.

No it’s absolutely not run by volunteers

It is a gym that caterers for adults and children

Did he "pass" the grading (not sure how it works!) I would just mention it to the manager that the time was wrong.
